Be itknown that I, DAVID GENEsE, a citizen of the United States, residing at Baltimore, in the State of Maryland, haveinvented new and useful Improvements in Covered Suppositories and Methods of Making Same, of which the following is a specification.

My invention relates to covered suppositories and method of making same, and has for its object to produce in a simple and economical mannera covered suppository comprising a medicinal substance, such as solidified glycerin, inclosed and securely sealed in an airtight manner in a removable envelop.

In proceeding according to my invention the glycerin or other similar substance is first molded to the desired shape to form the suppository. It is then inserted in a coneshaped envelop of tinefoil open at its larger end. Said envelop is then placed in a press or die having molds the shapeand size of the molded glycerin, and the envelop is compressed firmly and smoothly about the suppository, its open end being closed thereby and crimped and otherwise indented to seal such opening. To further seal the envelop and to cover or close any openings that may be therein due to imperfections in the metal, I next subject the envelop to a bath of an oxid of the metal of which it is composed, in the form, substantially, of a paste, which in the present instance would be oxid of tin, or otherwise coat the suppositorywith such oxid, as by painting, which by reason of its affinity for the metal of the envelop will adhere thereto,

Fig. 4 is a longitudinal section of the envelop shown in Fig. 1 with the suppository inserted therein. Fig. 5 shows in section the envelop containing the suppository inserted in a preferably made of tin-foil, although aluminium or other suitable metal may be employed. This envelop, except as .to its larger end 3, which is left open, is made as nearly imperforate as possible.

4 indicates a body of solidified glycerin or similar substance which has been molded to a cigar shape to form a suppository. This shape of the glycerin body is found desirable, for the reason that its sides and butt-end will fit snugly the interior of the envelop 1, and the large end of the envelop may be readily compressed about the curved pointed end 5 to present a smooth surface. This shape of the glycerin body is further desirable as facilitating the insertion of the suppository in the proper organ.

6 indicates the upper and The lower die of a suitable press, in each of which is a mold 8 of the size and shape of one-half of the suppository 4 should the latter be bisected longitudinally. In addition the die 6 is provided just beyond the pointed end of the mold 8 with a transverse feather or rib 9 and other ribs 10, and the lower die 7 is correspondingly recessed, as at 11, to receive said ribs. The suppository, inclosed in theenvelop 1, being placed on the lower die 7 inthe mold 8 thereof, as shown in Fig. 5, the upper die 6 is brought down upon or closely adjacentto said lower die, and as a result the envelop 1 will be firmly pressed about the suppository 4, and

the end portion 3 of said envelopwill be flattened out beyond the pointed end of the suppository, as shown in Fig. 7, the ribs 9 and 10 and the recesses 11 serving to crimp and seal the open end of the envelop, as indicated at 12, and to further indent the flattened-out portion of the envelop to take up the superfluous material,asindicated at 13. The metalcovered suppository is now coated in any suitable manner, as previously described, with an oxid of the metal of which the envelop is composed, such coating being indicated by 14in Fig. 8 and serving, as previously described, to cover or close any imperfections or openings in the envelop.

Having thus fully described my invention, what I claim as new is v 1. The method of covering suppositories which consists in forming an envelop ofa suitable metal, inserting the suppository therein, pressing the envelop about the suppository and closing the envelop, and then coating the envelop with an oxid of the metal of which it is composed.
